Find the mean proportion between :
18 and 8

Answer

To find the mean proportion between the numbers 18 and 8, we can follow these steps:

### Step 1: Understand the formula for mean proportion
The mean proportion between two numbers \( a \) and \( b \) is given by the formula:
\[ \text{Mean Proportion} = \sqrt{a \times b} \]

### Step 2: Assign values to \( a \) and \( b \)
In this case, we have:
- \( a = 18 \)
- \( b = 8 \)

### Step 3: Calculate the product of \( a \) and \( b \)
Now, we calculate the product:
\[ a \times b = 18 \times 8 \]

### Step 4: Perform the multiplication
Calculating \( 18 \times 8 \):
\[ 18 \times 8 = 144 \]

### Step 5: Take the square root of the product
Now, we find the mean proportion by taking the square root of 144:
\[ \sqrt{144} = 12 \]

### Conclusion
Thus, the mean proportion between 18 and 8 is:
\[ \text{Mean Proportion} = 12 \]
